Answer:
Step-by-step explanation:
x = 3y
x + y = 180°
3y + y = 180° ⇒ y = <em>45° = a</em>
x = 3( 45° ) ⇒ x = <em>135° = b</em>
Answer:
1
Step-by-step explanation:
12+[2-(4 × a²)] ÷ 7+b
= 12+[2-(4 × 5²)] ÷ 7+ 1
= 12+[2-(4 × 25)] ÷ 7+ 1
= 12 + (2 - 100)÷ 7 + 1
= 12 - 98 ÷ 7 + 1
= 12 - 14 + 1
= 1
Answer:
The portfolio beta is
Step-by-step explanation:
From the question we are told that
The first investment is
The first beta is
The second investment is
The second beta is
Generally the portfolio beta is mathematically represented as
substituting values
The lengths of the sides are 7, 23 and 24.
In order to find this, we need to add all of the side lengths together and set equa to 54. This will allow us to solve for n.
n + 3n + 2 + 4n - 4 = 52
8n - 2 = 52
8n = 54
n = 7
This gives us the length of the first side. To solve for the others, plug 7 into the equations.
3n + 2
3(7) + 2
21 + 2
23
Then the next one.
4n - 4
4(7) - 4
28 - 4
24
